Description

multi-disc butterfly valve is a type of valve designed for high-pressure or high-performance applications, often used in industries like oil and gas, water treatment, and power generation. It features multiple discs (or plates) that work together to regulate flow, offering better sealing and control compared to traditional single-disc butterfly valves.
Here are some examples of multi-disc butterfly valves and their applications:
1. High-Performance Multi-Disc Butterfly Valves
Application: Suitable for high-pressure and high-temperature environments, such as steam systems, gas pipelines, and power plants.
Features:
Multiple discs for improved sealing and reduced torque.
Robust construction with materials like stainless steel or carbon steel.
Fire-safe design for critical applications.
Example: Valves used in oil refineries or chemical processing plants.
2. Triple Offset Multi-Disc Butterfly Valves
Application: Ideal for critical applications requiring zero leakage, such as in LNG (liquefied natural gas) or cryogenic systems.
Features:
Triple offset design for minimal wear and friction.
Metal-to-metal sealing for tight shut-off.
Suitable for bi-directional flow.
Example: Valves used in offshore platforms or subsea pipelines.
3. Double Disc Butterfly Valves for Water Treatment
Application: Commonly used in water and wastewater treatment plants.
Features:
Two discs for enhanced flow control and sealing.
Corrosion-resistant materials like ductile iron or epoxy coating.
Easy to operate with low torque requirements.
Example: Valves used in large-diameter water distribution systems.
4. Cryogenic Multi-Disc Butterfly Valves
Application: Designed for extremely low-temperature applications, such as LNG storage or liquid nitrogen systems.
Features:
Specialized materials to withstand cryogenic temperatures.
Multi-disc design for tight sealing and minimal heat transfer.
Compact and lightweight for easy installation.
Example: Valves used in LNG terminals or aerospace industries.
